Dataset on airflow resistance of wings from owls and non-silently flying birds

The dataset contains measured airflow resistance values from prepared wings of owls and other, non-silently flying birds. It consists of a comma-separated values (CSV) file named "dataset_wingpermeability.csv" that contains 149 rows and six columns. The first row contains the header and the remaining 148 rows contain the raw data. The first column specifies the species (e.g. Barn owl, Tawny owl, Long-eared owl, Common buzzard, Eurasian sparrowhawk or Common pigeon) as a string format. The second column specifies the corresponding binomial name (e.g. Tyto alba, Strix aluco, Asio Otus, Buteo buteo, Accipiter nisus or Columba livia) as a string format. The third column contains the number of the wing, which have simply been numbered consecutively from 1 to 39 as integer data type. The fourth column specifies whether it is a left wing or a right wing, again as a string value. The next column contains the measurement position on the wing, which have been numbered from 1 to 4 as integers. The final column then contains the measured flow resistance R in Pa s/m³ as floating point values. The csv-file uses Unicode (UTF-8) character encoding and the fields are separated by commas. The corresponding figure is a Portable Document Format (PDF) file named "wingpermeability_boxplot.pdf". It shows the measured air flow resistances contained in the dataset as a box plot. It can be seen that, on average, the airflow resistance of the owl wings is significantly lower than that of the wings of the non-silently flying birds. A third figure ("measurement_positions.pdf") shows a photograph of one of the Barn Owl wings as an example, indicating the four the measurement positions on the pressure side of the wing.
